In spite of a patched-up reconciliation with the king, Becket proceeded to excommunicate or suspend some of the great English prelates and, as Henry believed, was conspiring to rob his son of the crown. In a fit of anger, Henry exclaimed among his followers, "Is there no one to avenge me of this miserable clerk?" Unfortunately certain knights took the rash expression literally, and Becket was murdered in Canterbury cathedral, whither he had returned. The king had really had no wish to resort to violence, and his sorrow and remorse when he heard of the dreadful deed, and his terror at the consequences, were most genuine. The pope proposed to excommunicate the king. Henry, however, made peace with the papal legates by the solemn assertion that he had never wished the death of Thomas and by promising to return to Canterbury all the property which he had confiscated, to send money to aid in the capture of the Holy Sepulcher at Jerusalem, and to undertake a crusade himself.[92] [Sidenote: Richard the Lion-Hearted, 1189-1199.] [Sidenote: John, 1199-1216.] 54. Henry's later years were troubled by the machinations of Philip Augustus of France and by the quarrels and treason of his own sons, of which some account has already been given.[93] He was followed by his son, the picturesque Richard the Lion-Hearted, one of the most romantic figures of the Middle Ages. He was, however, a poor ruler, who spent but a few months of his ten years' reign in England. He died in 1199 and was succeeded by his brother John, from all accounts one of the most detestable persons who has ever worn a crown. His reign was, nevertheless, a notable one in the annals of England. In the first place, he lost a great part of the possessions of his house upon the continent (Normandy, Brittany, Anjou, etc.); secondly, he was forced by a revolt of his people, who refused to endure his despotism any longer, to grant the Great Charter. The loss of his lands across the Channel has already been described; it remains only to speak of the winning of the Great Charter of English liberties.[94] [Sidenote: The granting of the Great Charter, 1215.]
